101342018-10-10Integrated Data Assimilation Architecture, Phase ICompletedJan 2006Jan 2007The Integrated Data Assimilation Architecture (IDAA) is a middleware architecture that facilitates the incorporation of heterogeneous sensing and control devices into a unifying system with standardized application interfaces. The architecture is standards-based (IEEE wireless standards) and is an open architecture that can be easily extended. This system is innovative from several perspectives: (1) the design explicitly supports multiple disparate devices ? to date, wireless middlewares have focused on single device types or single network types; (2) independent development is explicitly supported by means of a published application programmer interface (API) along with system client libraries that provide standard services; and (3) a Development Kit ("DevKit") that includes working examples and source code templates is provided to assist developers in the integration of a new monitoring device and/or the composition of a new application that is a consumer of the data produced by the system. The proposed system will support the T3.01 Aerospace Communications topic by delivering a hybrid architecture that by design can incorporate multiple heterogeneous wireless devices and networks. Additionally, the IDAA system provides for multi-developer system extensibility, alleviating the problem of a monopolistic single-vendor implementation, where only the original developer of the middleware can efficiently extend the system functionality.SBIR/STTRSpace Technology Mission DirectorateGlenn Research CenterGRCNASA CenterClevelandOHInvocon, Inc.IndustryConroeTXOhioTexasTherese GriebelCarlos Torrez
